The city's lead service line program
The City of South St. Paul reports that, as of October 17, 2025, its inventory counted about 740 lead service lines and about 175 galvanized lines that require replacement. The city says private-side replacement may be done at no cost to the owner with a signed agreement.
Before you pay for a replacement, call the city to ask whether your address is on the inventory and whether you qualify. We can handle the work if the program does not apply, or coordinate with the city's contractor if it does.
Signs of a service line problem
A buried leak rarely shows up as a gusher. Look for a soft or unusually green patch in the yard, a drop in pressure at every fixture, a meter that moves with all fixtures off or a rise in your usage on the bill.
A meter test helps. If the meter spins when everything inside is closed, the leak is on the service line or inside the house. Leak detection sorts out which.
Repair, replace or trenchless
The right option depends on the break and the yard.
| Option | Best for | Notes |
|---|---|---|
| Spot repair | One localized break in good pipe | Needs a dig at the break |
| Open-trench replacement | Lead, galvanized or failing old line | Surface restoration needed |
| Trenchless replacement | Long lines under driveways or trees | Needs entry points and suitable soil |
Gopher State One Call, 811, locates buried utilities. Plan for at least 48 hours' notice before digging.
Depth, frost and planning the dig
Minnesota's plumbing code in chapter 4714 requires buried water piping to sit at least 12 inches below local frost depth. For Dakota County the state frost depth is 3.5 feet, so a service line trench is about 4.5 feet deep.
That depth is why this is not a weekend project. We locate utilities, plan the trench around trees and driveways and restore the surface. If the break happened in winter, ask us about burst pipe repair timing, because frozen ground slows the dig.
